optimbase_isfeasible

Checks if the point satisfies constraints.

Calling Sequence

[opt, isfeasible] = optimbase_isfeasible(opt, x)

Argument

opt

The object of TOPTIM type (tlist).

x

A vector of doubles. The current point.

isfeasible

An integer either -1, 0 or 1.

Description

The optimbase_isfeasible function checks if the point x satisfies the bounds and inequality constraints.

This function returns

  • 1 if the given point satisfies bounds constraints ans inequality constraints,

  • 0 if the given point is not in the bounds,

  • -1 if the given point does not satisfies inequality constraints.

Example

opt = optimbase_new ();
opt = optimbase_configure(opt, "-numberofvariables", 2);
opt = optimbase_configure(opt, "-verbose", 1);
opt = optimbase_configure ( opt , "-boundsmin" , [-5 -5] );
opt = optimbase_configure ( opt , "-boundsmax" , [5 5] );
[ opt , isfeasible ] = optimbase_isfeasible ( opt ,  [0 0] );
disp(isfeasible)
opt = optimbase_destroy(opt);
